Control of interlayer excitons in two-dimensional van der Waals heterostructures
TL;DR: A device capable of inverting the polarization of light by efficient control of interlayer excitons in a van der Waals heterostructure is demonstrated, representing an important step towards implementing logic operations in valleytronics.
Journal ArticleDOI
Nanomechanics of carbon nanotubes
Andras Kis,Alex Zettl,Alex Zettl +2 more
TL;DR: This work has characterized the mechanical properties of carbon nanotubes using scanning probe microscopes and shown that stiff sp2 bonds result in a Young’s modulus close to that of diamond, while the relatively weak van der Waals interaction between the graphitic shells acts as a form of lubrication.
Journal ArticleDOI
Micro-reflectance and transmittance spectroscopy: a versatile and powerful tool to characterize 2D materials
Riccardo Frisenda,Yue Niu,Yue Niu,Patricia Gant,Aday J. Molina-Mendoza,Robert Schmidt,Rudolf Bratschitsch,Jinxin Liu,Lei Fu,Dumitru Dumcenco,Andras Kis,David Perez de Lara,Andres Castellanos-Gomez +12 more
TL;DR: In this paper, the authors describe a versatile optical microscope setup for carrying out differential reflectance and transmittance spectroscopy in 2D materials with a lateral resolution of ~1 µm in the visible and near-infrared part of the spectrum.
Journal ArticleDOI
Disorder engineering and conductivity dome in ReS2 with electrolyte gating.
Dmitry Ovchinnikov,Fernando Gargiulo,Adrien Allain,Diego Pasquier,Dumitru Dumcenco,Ching-Hwa Ho,Oleg V. Yazyev,Andras Kis +7 more
TL;DR: Theoretical calculations and a transport model indicate that the observed conductivity suppression can be explained by a combination of a narrow conduction band and Anderson localization due to electrolyte-induced disorder.
Journal ArticleDOI
Valley-polarized exciton currents in a van der Waals heterostructure
Dmitrii Unuchek,Alberto Ciarrocchi,Ahmet Avsar,Zhe Sun,Kenji Watanabe,Takashi Taniguchi,Andras Kis +6 more
TL;DR: The generation and transport over mesoscopic distances of valley-polarized excitons in a device based on a type-II TMDC heterostructure is shown and electrostatic traps are used to increase the exciton concentration by an order of magnitude, opening the route to achieving a coherent quantum state of valley, polarizedexcitons via Bose–Einstein condensation.
